I just beat Lasota at Dice Poker, and if I read everything correctly I asked for a 'tempered steel (armor?) schematic'. What I got was, I don't know? I received something, because it put me over my 250 weight limit, but I don't know what I received.

Anyone else run into this?

I just did the same thing and picked the same reward. But I can't find any new armor schematics so I'm not sure what he gave me.

Also, for the chaper 2 fist fighting quest (Against the Blue Stripes) the journal said they game me a sword but I can't find that either.

I don't recall getting a sword...

There's also an issue with the dwarf outside of Vergen you play dice with, he claims to have given you a sword but you don't actually receive anything. He also gives you some sort of Dun Banner cloak which I haven't found a use for (just a plain Quest Item).

the sword he gave is also a quest item

It just happen to me I chose the schematic for tempered armor but I didn't found any new armor schematic, but I did notice a second schematic for hardened leather that I didn't have before. Which is pretty useless cause that's just a crafting ingredient which I bough already for around 130 orens.
Edit
I just confirm the quest reward is missleading for beating Lasota on dice I did 4 reloads to beat him 4 times and check each reward choosing studded leather armor gives the diagram for studded leather ingredient (275) orens if you buy it from him, leather armor you get the diagram to make leather ingredient worth (175) orens, and tempered armor gives digram for hardened leather crafting ingredient worth (205) orens. If you choose the gold you get 205 orens which I did point find each of the rewards to be lame. The troll in chapter 1 gave me a better reward.
